第 8 章 配置 RBAC 策略

流程

1. 确认为您的云设置了系统 OS_CLOUD 变量：

   $ echo $OS_CLOUD
   my_cloud

   如果需要，重置变量：

   $ export OS_CLOUD=my_other_cloud

   作为替代方案，您可以在每次运行 openstack 命令时添加 --os-cloud <cloud_name > 选项指定云名称。

2. 查看可用网络列表：

   $ openstack network list

3. 查看项目列表：

   $ openstack project list

   Copy to Clipboard Toggle word wrap

   +----------------------------------+----------+
   | ID                               | Name     |
   +----------------------------------+----------+
   | 4b0b98f8c6c040f38ba4f7146e8680f5 | auditors |

4. 为 web-servers 网络创建一个 RBAC 条目，以授予对 auditors 项目的访问权限(4b0b98f8c6c040f38ba4f7146e8680f5):

   $ openstack network rbac create --type network --target-project 4b0b98f8c6c040f38ba4f7146e8680f5 --action access_as_shared web-servers

   | Field          | Value                                |
   +----------------+--------------------------------------+
   | action         | access_as_shared                     |
   | id             | 314004d0-2261-4d5e-bda7-0181fcf40709 |
